It's your job to fix the network.
So at the moment, based on this configuration, it looks like this router has been fixed, show version
again shows us that the configuration register is set to this, which is the way we want it set.
So to confirm things we could do, reload here and verify that the router boots successfully.
OK, so on router 1, we've been prompted whether we want to enter the initial configuration dialog,
I'm going to say No,
press return to get started.
We've been able to get into the router, but there's no configuration, just a standard default configuration
exists on the router.
As an example, there are no IP addresses, there are no routing protocols running on the router, router
2 once again has booted successfully.
So that's good news.
OK, so on router 1, why did it boot and not load the startup configuration?
Why did we get prompted
with the system configuration dialog or initial configuration dialog, show version, I'll make this
bigger and scroll down, can you see the problem here?
Notice the configuration register is set to 0x2142,
that again configures the router to ignore NVRAM, in other words, ignore the startup configuration.
So we're going to want to change that, so config register 0x2102 show version, currently
this is the configuration register,
this will be the configuration register at next reload, type reload.
We definitely don't want to save the running configuration now because otherwise
and I'll just exit out of this,
otherwise, we are going to be overriding this startup configuration
with this default running configuration, which we definitely don't want to do. So show startup-config
shows us a full startup configuration, including a configuration for EIGRP.
The running configuration doesn't have any of that.
We have changed the configuration
register to this at next reload.
So when we reload, we want to make sure that we enter no here and then press enter to confirm reboot.
So the router should boot normally and load the startup configuration into running configuration when
it boots up.
We can see that it's done that noticed press return to get started and EIGRP neighbor relationship has
been established to router 2, notice the router name is router 1.
We have a password, which in this case is Cisco, show run shows us the configuration of the router.
So a configuration has been set.
So show IP interface brief.
We have an interface up,
interfaces down currently to router 3 loopback is up, loopback of router 2 is this.
I can ping the loopback of router 2 and router 2 can ping the loopback of router 1.
So we've got these two routers restored.
Show version, configuration register is now this, startup configuration is still there, so that's good.
Let's have a look at router 3.
